"Precisely. Herr Rix," he exclaimed, addressing the Leutnant. "Take four men and go ashore. Von Ruhle will tell you where these English boys are; have them brought on board."
"One moment," interrupted Ramblethorne. "They came to the island in a boat. There is nothing unusual in that, I admit, but the fact remains that the boat is still lying in the cove next to this. You might order the men to set the boat adrift."
"Water-logged, and with sails set and the main-sheet made fast. Another deplorable accident. Ach! It shall be so."
Half an hour later Ross Trefusis and Vernon Haye, still unconscious under the action of the anaesthetic injection, were brought on board U75 and passed below. Their boat, lying on its beam-ends, was drifting slowly in the direction of Black Bull Head. Ramblethorne and von Ruhle, their work for the present done, were already on the way to the mainland.
Meanwhile, alarmed at the non-appearance of the young heir to Killigwent Hall and his guest, a party had set off to search St. Mena's Island.
Just as the boat's keel grounded on the beach of Half Tide Cove, the German submarine slipped quietly through the blurr of misty rain, and under cover of darkness headed towards the mouth of Bristol Channel.
